Frequently Asked Questions

Q: Whats the difference between Pelican & Storm Cases ?

  • Whats the difference between Pelican™ & Storm™ ?
  • Pelican accuired Hardigg Industries (makers of Storm cases) in 2009. Now "Pelican-Storm" these cases are similar in size and price, but offer a slightly different look. See the link above for style differences.

Q: What materials are the cases made from ?

         A: The cases are made out of a Polypropylene copolymer material that is light weight, durable and highly chemical resistant.

Q: How does the Pick'N'Pluck foam work ?
A: The video below will give you an idea on how this works. The foam layers have pre-scored cuts that you break away to the desired shape of your device.

Q: What temperatures can the cases tolerate?

A: The cases (MIL SPEC) will withstand temperatures from -10°F (-23.3°C) to +210°F (98.9°C).

Q: What adhesives and/or paints can be used on the cases?

A: Due to the nature of the polypropylene being chemically inert, very little will attack the material.  That also means that very few adhesives and paints will adhere satisfactorily.  For an adhesive, we have found that 3M’s DP-8005 two-part adhesive works very well with our case material.

Q: Are there any hazardous substances in the case material?

A: RoHS, or “Restriction on Hazardous Substances” - RoHS specifically bans or restricts the use of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated biphenyl ethers (PBDE).  At the July 1, 2006 implementation of the RoHS provisions, Pelican cases will not contain the banned or restricted materials and will therefore be RoHS compliant.  NOTE: Directive 2000/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances in electrical and electronic equipment – is aimed at reducing the hazardous materials content in electronic products as well as increasing the recycling efforts for these products.

Q: How does the Pressure Equalization Valve work?

A: The Pressure Equalization Valve is a simple device.  It consists of a housing with a hole through it that is covered with a thin Gore-Tex® membrane.  According to the Gore™ tech sheet: “The microporous expanded polytetraflouroethylene (ePTFE) membrane continuously allows the free passage of gases and vapors, equalizing the pressure differential between the enclosure and ambient before it builds to the point that a seal is compromised.  Water, dust and dirt are repelled by the hydrophobic membrane, thereby protecting expensive and sensitive electronics.”
Q: Can I change the Automatic valve (SKU: 1209AUTO) to a manual valve (SKU: 1209)?
A: These are not made to be easily changed so in short the answer is no however If you are prepaird to do it here is what you will need to do. Use a wide blade screw driver to carefully lift out the existing valve, you will need to work around the valve and twist the screw driver a little to start lifting it out. Drill the existing hole to 8.3mm (DO NOT try any larger as the brass lug will fall out).
You will need two parts (1209BL - Brass Lug & 1209 - Manual Valve with O-Ring). You will see on the brass lug their is a small lip around the top, this needs to be counter sunk so that it fits flush with the case frame on the outside of the case. To do this you can use a larger drill just to take the top off a little (about 1mm). Insert the the brass lug and screw in the valve. Ensure the o-rings fits flush against the case.

Q: What is the o-ring made of?

A: The o-ring is made of EPDM or Ethylene Propylene Diene Monomer.  It is well known for its excellent ozone, weathering and aging resistance.  It also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids and oxygenated solvents and is very color stable.  (It is not recommended for resistance to oil, gasoline and hydrocarbon solvents.) EPDM is found in a wide range of applications and is excellent for use outdoors.
Q: What does IP67 mean ?
A: The two digits represent different forms of environmental influence:

 • The first digit represents protection against ingress of solid objects.
 • The second digit represents protection against ingress of liquids.

The larger the value of each digit, the greater the protection. As an example, a product rated IP54 would be better protected against environmental factors than another similar product rated as IP42.

IP.. First digit:
Ingress of solid objects
Second digit:
Ingress of liquids
0 No protection No protection
1 Protected against solid objects over 50mm e.g. hands, large tools. Protected against vertically falling drops of water or condensation.
2 Protected against solid objects over 12.5mm e.g. hands, large tools. Protected against falling drops of water, if the case is disposed up to 15 from vertical.
3 Protected against solid objects over 2.5mm e.g. wire, small tools. Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical.
4 Protected against solid objects over 1.0mm e.g. wires. Protected against splash water from any direction.
5 Limited protection against dust ingress.
(no harmful deposit)
Protected against low pressure water jets from any direction. Limited ingress permitted.
6 Totally protected against dust ingress. Protected against high pressure water jets from any direction. Limited ingress permitted.
7 N/A Protected against short periods of immersion in water.
8 N/A Protected against long, durable periods of immersion in water.
9k N/A Protected against close-range high pressure, high temperature spray downs.
